It occurs in a single locality in Dnipropetrovsk Oblast, Ukraine, where it grows on the vertical surfaces of black schist beside a river.

The species epithet panticapaensis recalls the word Panticapa, which is the Ancient Greek name for the Inhulets river in Ukraine.

[1] The crustose thallus of Lecanora panticapaensis ranges in colour from grey to greyish-yellow top yellow-green, and reaches a diameter of up to 10 cm (3.9 in) wide.

Apothecia occur frequently, and are 0.8–1.2  in diameter; they are lecanorine in form with a flat, brown disc encircled by a margin of the same colour.

[1] Lecanora panticapaensis is only known from the type locality, a riverine habitat lined with vertical schist rocks.
